Allergy Research Group Prima Uña de Gato II contains cat's claw (Uncaria tomentosa) extract containing 3% total alkaloids. Minerals and enzymes are added to the formula. 

Prima Uña de Gato II #75041 replaces Prima Uña de Gato #75040, with one significant change: the cat’s claw ingredient is changed from a powder to a high quality 4:1 extract, which has increased total alkaloid content. The other active ingredients remain the same.
